. IMPROVEMENT IN B'L'A'CKSMITHS COMBINED MACHINES.

Specification forming part of Letters Patent No. 199,741, dated January 29, 18.78; application iiled i Y September 3, 1877.

To all whom t maycohcem:

Beit known that I, AUeUsT Pinon, of the city of Denver, in the Stateof Colorado, have the devices may be operated by the same driving power, whether hand power or otherwise, and great convenience is attained.

Referring to the drawings forming part of this specification, Figure l is a side elevation of the machine. Fig. 2 is a front end elevation; Fig. 3, a vertical longitudinal section, Fig. 4, a top or plan view, Fig. 5, a rear end elevation Fig. 6, a section on the line w a, and Fig. 7 a section on the line y y.

The parts of the machine are represented as follows: A, frame-base, B, frame-pillar, and C frame-top, all preferably made in one solid piece; D, stock for insertion of a drill, punch, or mortising-chisel; E, adjustable tire-shrinker; F, scroll-saw G, circular saw; H, adjustable power-hammer; I, swage or reamer; K, shears; L, tire-bender; M, vise. j The machine is intended to be operated by hand or other power, the handle a for the former and the pulley b for the latter. For ordinary drilling, punching, mortising, tire bending and upsetting, and metal cutting or shearing, hand-power is sufficient. For circular and jig sawing, heavy swaging, hammering and punching, power can be applied to the pulley.

Power is transmitted directly, by means of the gear-wheels c d e,vto the shaft f, for the purpose of operating the circular saw, tireshrinker, and the tire-bender; and power is further transmitted indirectly, by means of an eccentric, g, to operate the scroll-saw, swage, power-hammer, shears, punch, and chisel. The crank also, by means of the angle-gear h fastened to its shaft, operates the drill. When power is applied to the pulley `it is transmitted, by means of the bevel wheel k onl the shaft of the tool-stock D, to the bevel-wheel h, and thence, throughthe cog-wheels c d e, to the main shaft, for operating the devices described. When it is def sired to run only the drill, the gear-wheel d is pressed toward the frame and thrown out of gear with the wheels c and e. The hand. wheel l is for operating the parallel feed mechanism which raises and lowers the tool-stock. The `upper end of the stock has an annular groove to receive a set-screw in the yoke con! necting the lower ends of the adjusting-screws 3 3. By turning the wheel Z to the right or left the cog-wheels 4 4 will be operated, and the parallel screws will lower or raise the toolstock by means of the yoke, the annular groove, and the set-screw.

The vise is inserted in V-shaped ways m m in the frame, and is therefore horizontally adjustable with reference to the tool-stock, so that a greater range of holes may be made by shifting the vise. By means of parallel twin screws and connecting cog-wheels a square clamp in the vise is obtained, and the tool in the'tool-stock unobstructed as it passes between the screws. The vise may be removed or retained in position when great power is applied. A platform, provided with a treadle having a vertical 1notion,may be employed as an auxiliary attachment.

The fulcrum of the power-hammer is at mat the tool-stock end of the frame. The hammer is adjustable on its lever P by means of a slot, o, in the body of the hammer, and a set-screw, p, so that the travel of the hammer may be varied. A nat-faced hammer is shown; but as the face is detachable, by taking out the bolt q a face of any desired shape-as convex, concave, a rightV or left bevel, or any other shape-may be substituted. The anvil 5 is also removable, and may be replaced by another with a surface corresponding to the face of the hammer. In a continued motion of the machine the travel of the hammer would be limited to its adjustment, and it would be the same at each stroke; butin a partial motion of the machine, by turning the crank back and forth, the travel of the hammer is not limited, and a succession of variable blows may be struck,as in hammering.

The shears are adjustable, and easily removable for sharpening or substitution, and

are so located as to be very effective with little power. opposite the shears y(shown in dotted -l ines)` serves to aid in cutting metal a given length, and to hold it from iiying up, insuring a square cut.

The tool-stock, when rotating, is disconnected from the lever P and keyed to the bevel-wheel k, which imparts rotary motion. When the tool-stock is reciprocated with a punch or chisel, it is disconnected from the bevel-wheel and pinned to the lever, which gives it vertical motion.

rIhe tire shrinker or upsetter is fastened at its base to an arm, u, ofthe frame. Its upper ends are free, and are provided with a tongue, G, and a groove, 7, and cog-segments 8 and 9, between which rotates a gear-wheel, w, on the main shaft. When a heated tire is placed in the upsetterfor shrinkage, motion is given to cog-segments, and they are drawn in opposite directions, which causes the tongue 6 to enter the groove 7, and consequently the circular shrinker to be contracted, and the tire within correspondingly pressed and shrunk.v

In the upper part of the frame are two rollers, L L, for tire-bending, for which purpose the eccentric g must be removed and a similar plain roller placed in its stead on the The gage s on the side of the frame shaft, to revolve with it. The hand-wheel Z should also be removed. The tire must be partially bent and placed under the middle roller, the ends projecting above and resting upon the outside rollers. The motion of the roller on thevmain shaft will draw the tire and cause it to be curved as it is passed under the middle roller. By placing the rollers nearer together or farther apart, the size or curve of the tire may be varied.

I claim as my inventionl. The combination of the main frame, the tool-stock, bevel-wheel k, feed mechanism 3 3 4 '4, and driving-gear, substantially as and for the purpose set forth.

2. rIhe combination of the main frame AB C, lever P, eccentric g, shaft j', tool-stock D, and driving-gear, relatively located `and adapted, as set forth, for the operation of a hammer, shears, swage, reciprocating saw, punch, and

' chisel, substantially as shown and described.

In witness whereof I hereunto subscribe my name in the presence of two attesting witnesses this 27th day of August, 1877.
